For conserving space behind the panel, the LP01 Series illuminated/non-illuminated pushbutton switches feature a behind-panel depth of 14 mm. In addition, the cap diameter is 13.6 mm, making the overall diameter including the housing just 20 mm. A unique design and construction prevents cap removal, limiting the risk of tampering. Available in both single- and double-pole momentary versions, a unique arc barrier allows two different voltages to be used in the double-pole configuration. Other features include a mechanical life of 500,000 operations minimum, ratings of 3A at 125/250 Vac or 3A at 30 Vdc, and UL94V-0 flammability ratings. NKK SWITCHES, Scottsdale, AZ. (480) 991-0942.
